MoToRfGENEEAToR SET.

Specication of Letters Patent.

' Patented July 6, 1915.

To all whom 'it may concern.'

Be it known that I, CHARLES W. DARE, a citizenof the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Motor-Generator Sets, of which the following is a specification.

My invention relates to motor generator sets and is illustrated in the accompanying drawing wherein the .drawing represents a motor generator set in elevation, parts being shown in longitudinal section.

A is a base and standard on which is mounted the two part generator casing B into which projects one end of the shaft C on which is mounted within the casing the generator armature. The shaft C is provided with a bearing beyond which its end projects into the generator case. This bearing consists of thel ball bearing structure D held in position against the shoulder D1 on the shaft and between the flange D2 of the sleeve D3 which surrounds the shaft. This flange D2 is -held in position by the cap DA1 secured by the cap screws D5 to the end plate F.

The cylindrical housing F1 carries at one end the inwardly projecting flange F12 which ange carries the collar F projecting outwardly from the end of the housing and the collar F13 located behind the collar F. The collar F13 is, of course, perforated as indicated, the perforation being of such diameter as to permit the passage of the shaft C. The wall of the perforation in opposition to the shaft C consists of the oil retaining grooves F14 forming in effect a stuffing box to prevent or minimize the discharge of greaseout of the grease chamber F13. The conical extension o enlargement F2 which connects the sleeve F1 and the motor casing G is integral with each of them but apertured at F3 to provi e access for the stuffing box F'1 made up of the sleeve Fi located in the diaphragm F and the screwthreaded nut or collar F7 screwthreaded on the end of the sleeve and compressing and.v

the shaft casing and provided with the baiseand standard-G1 on which it is mounted. It contains the motor which in the preferred form of my device is a steam turbine. Beyond the motor casing is a bearing casing J secured to the motor casing by the cap screws J1 J 1 and provided with the housing J 3 in which the other bearing J3 of the shaft C is located.

The parts can be easily assembled or disassembled and this is effected without disturbing their relations or the arrangement of their several parts.

I claim:

A motor generator set comprising a motor housing and a generator housing, a sleeve integral with 'the motor housing abutting against the side of the generator housing and means for holding the sleeve and generator housing in fixed relation one with the other, a bearing in the side wall of the motor housing farthest removed from the generator housing, a bearing in the side wall of the generator housing adjacent the motor housing, a shaft mounted on said bearings, an apertured dividing wall interposed be tween the motor and generator, a packing gland in said aperture surrounding said shaft, an apertured wall at the end l of the sleeve adjacent the generator housing and a grease pocket contained within said apertured wall and in communication with the bearing in the`generator housing wall and grease retaining rings on the wall of the aperture in the end of the sleeve surrounding the shaft.

Signed at Chicago, Illinois, this 10th day of June, 1912.
